Satake Shoji had been a trapeze artist in the Ezaki Circus, but when Shingo, his team mate, slipped and fell to his death, he had felt responsible and, sick at heart, left the circus for a life at sea. On land again Shoji goes to a cabaret where he is soon involved in a brawl. Kasamatsu, the owner of the cabaret, impressed by Shoji's strength, offers him a job as his bodyguard. The next morning Shoji visits Shingo's grave and meets Miyako, Shingo's former sweetheart, who is still a trapeze performer and now the star of the Kuroko Circus which Shoji realizes Kasamatsu intends to control.
